Abstract

In this study a 1000 MW NGCC power plant has been intEGRated with post-combustion CO2 capture and compression process to mitigate its emission. The MEA-based CO2 capture process was designed for 90% CO2 separation. The detailed models of the power plant, CO2 capture and compression process were developed in Aspen HYSYS v9 in order to analyse the performance of the intEGRated system. Three cases of intEGRation have been investigated. In the first case, the power plant net thermal efficiency was decreased from 62. 5% to 53. 4%. This efficiency drop due to steam extraction from the power plant to provide reboiler duty and power consumption by capture and compression process. The effect of exhaust gas recirculation (EGR) on the plant performance was studied in the second case. EGR implementation and waste heat recovery by organic Rankine cycle in the third case led to an increase of 1. 56% in the power plant efficiency in comparison with the first case. The CO2 emission of the power plant was decreased from 324. 71 g/kWh to 36. 71g/kWh in the third case of intEGRation.
